I tried to solve this distance speed and time question, but I got quite stumped?

#4km"/"h# is Misha's speed

You can calculate the third value in questions involving distance, speed, and time if you know two of the three values.

The equation is:

#"Speed" = "Distance"/"Time"" "larr# this gives 3 formulae:

#S =D/T" " and" "T=D/S" "and" " D= SxxT#

Regarding Dina:

#D=10km" "and" "S=5km"/"h#

Find the #"Time"# she took: #" "T= 10/5 = 2 hours#

Regarding Masha

#D = 8km" "#(she still had 2km of the 10km left to cycle)

#T = 2 hours" "#(Dina and Masha started at the same time)

#S = D/T = 10/2 = 4km"/"h#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
